CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. patent application Ser. No. 11/686,207, filed on Mar. 14, 2007 and entitled, “A HAND-HELD, PORTABLE ELECTRONIC DEVICE WITH A RETAINER PORT FOR REMOVABLY COUPLING AN ATTACHABLE WIRELESS AUDIOPHONE THERETO”

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to hand-held, portable electronic devices, and more particularly, to providing an audiophone retainer for headphone(s) and/or microphone using a hand-held, portable electronic device.

2. Description of the Related Art

Increasingly use to hand-held, portable electronic devices, such as a processor or controller based devices including hand-held, portable computers, hand-held multi-media players, music players, cellular phones, hand-held wired and/or wireless communication and/or computing devices, hand-held pocket computers, and personal digital assistants is becoming widely popular. As a result, use and exchange of electronic entertainment content and information is not only a trend anymore but a norm and a convenient way of experiencing multi-media content such as music and video, conveying information including electronic mail messages between users of wired and/or mobile communication devices. Many commercial enterprises, media service providers or network operators, Internet service providers and businesses use Internet to disseminate electronic multi-media content (textual, graphic, music and video files) over a connected mesh of wired and/or wireless network users. For example, several of these entities usually provide access to multi-media content and services on the Internet via websites and web browsers.

Users of the hand-held, portable electronic devices obtain and store a variety of electronic multi-media content such as music and video files on their hand-held, portable devices. Likewise, users of networked devices wired and/or wireless exchange electronic messages to communicate with other users. To use the hand-held, portable electronic devices, an audiophone comprising headphone(s) and/or microphone is provided for users. In general, for listening to electronic multi-media content such as music and video files, a pair of stereo headphones is provided with the hand-held, portable electronic devices. For the hand-held, portable networked, wired and/or wireless communication and/or computing devices, a headphone with a microphone is provided. Examples of headphones and/or microphones include a wired or a wireless set of audio devices.

While the wireless headphones and/or microphones comprise a headphone and/or a microphone, the wired headphone(s) and/or microphone comprise a pair of stereo audio cords with a set of micro headphones at one end and an audio male connector pin on the other end, both face a similar set of issues relating to their storage for reuse, i.e., when not being used by users. In particular, the audio cords are a few feet long so that a user can conveniently use the headphones and/or microphones. Since these audio cords are relatively soft and flexible they get entangled when the headphones and/or microphones are not being used. That is, storage of the headphones and/or microphones with a relatively long and flexible audio cord with headphone speaker(s) attached to its end is a messy affair. With regard to the wireless headphones and/or microphones, because of their wireless convenience it is relatively easy to misplace, damage, or loose them when they are not being in use. In this manner, storage for reuse of both the wired and/or wireless headphones and/or microphones of the hand-held, portable electronic devices becomes quite a challenge when an audiophone is not put to use by wireless users or it discharges rather quickly due to a constant use and need frequent recharging.

At the hand-held, portable electronic device 100, the CODEC 188 a may be coupled to the storage 170, which may, in turn, couple a device speaker 110 b and a device microphone 112 b to the system data bus 175. The hand-held, portable electronic device 100 may include one or more communication (COMM) port(s) 190 including a Universal Serial Bus (USB) port and a power and/or charging port. Using the COMM port(s) 190, for example, the hand-held, portable electronic device 100 may interface with external devices, such as computers or a base unit.

The hand-held, portable electronic device 100 may interface with computers, commercial enterprises, media service providers or network operators, Internet service providers and businesses using Internet to obtain and/or disseminate electronic multi-media content (textual, graphic, music and video files) over a connected mesh of wired and/or wireless network users. For example, a user of the hand-held, portable electronic device 100 may access multi-media content and services wirelessly or on wired communication medium on the Internet via websites and web browsers.

For illustrative purposes, in one embodiment, the hand-held, portable electronic device 100 may communicate over a communications system that may be a digital cellular network, although it should be understood that the present invention may be applicable to other systems that support data and/or voice communication. The communications system may allow the hand-held, portable electronic device 100 to communicate with a data network, such as the Internet, through one or more base stations (BTS). The hand-held, portable electronic device 100 may take the form of any of a variety of devices capable of accessing the data network through the BTS. In one embodiment, a plurality of the BTSs may be coupled to a Radio Network Controller (RNC) by one or more connections, such as T1/E1 lines or circuits, ATM circuits, cables, optical digital subscriber lines (DSL's), and the like. Generally, the RNC operates to control and coordinate the BTSs to which it is connected. The RNC is, in turn, coupled to a controller (CN) via a connection, which may take on any of a variety of forms, such as T1/E1 lines or circuits, ATM circuits, cables, optical digital subscriber lines, and the like.

The data network may be a packet-switched data network, such as a data network according to the Internet Protocol (IP). One version of IP is described in Request for Comments (RFC) 791, entitled “Internet Protocol,” dated September 1981. Other versions of IP, such as IPv6, or other connectionless, packet-switched standards may also be utilized in further embodiments. A version of IPv6 is described in RFC 2460, entitled “Internet Protocol, Version 6 (IPv6) Specification,” dated December 1998. The data network 125 may also include other types of packet-based data networks in further embodiments. Examples of such other packet-based data networks include Asynchronous Transfer Mode (ATM), Frame Relay networks, and the like. As utilized herein, a “data network” may refer to one or more communication networks, channels, links, or paths, and systems or devices (such as routers) used to route data over such networks, channels, links, or paths. It should be understood that the configuration of the communications system may include a network management system (not shown) that provides operation, administration, maintenance, and provisioning functions for a cellular network.

In other embodiments, Bluetooth may enable the hand-held, portable electronic device 100 to communicate over wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency. By using short-range radio frequencies Bluetooth may enable two or more devices, for example, the hand-held, portable electronic device 100 to communicate with another device in close proximity. For example, the audiophone 205 may be a Bluetooth headset capable of transferring files from phones/PDAs to computers. The Bluetooth specification is available from Bluetooth Special Interest Group (SIG) or as IEEE standard 802.15.1. Alternatively, Wi-Fi may be used in the hand-held, portable electronic device 100 to communicate on the same radio frequencies as Bluetooth, but with higher power consumption resulting in a stronger connection. Wi-Fi is sometimes called “Wireless Ethernet”. Bluetooth and/or Wi-Fi may be used in the hand-held, portable electronic device 100 within offices, homes and on the move by setting up networks, printing, or transferring presentations and files from PDAs to computers.

In operation, a user of the hand-held, portable electronic device 100 such as a media player may display a list of available media items on the display screen 145 to play a particular media item. By using the user COMM I/O interface 160, a user can select one of the available media items. The processor 140, upon receiving a selection of a particular media item, supplies the media data (e.g., audio file) for the particular media item to the CODEC 188 a. The CODEC 188 a then produces analog output signals for the speaker 110 b. The speaker 110 b can be a speaker internal to the hand-held, portable electronic device 100 or external to the hand-held, portable electronic device 100. For example, headphones or earphones that connect to the hand-held, portable electronic device 100 would be considered an external speaker. Accordingly, the processor 140 controls the playing of the particular media item such that upon receiving the user's selection of the particular media item, such as music file in Moving Picture Experts Group (MPEG)-1 Audio Layer 3 (MP3) format or MPEG-4 format based on International Organization for Standardization (ISO)/International Electro-technical Commission (IEC) JTC1/SC29 WG11 standard or M-JPEG used by Internet Protocol (IP) based video cameras via Hypertext Transfer Protocol (HTTP) streams by using multipart and/or mixed content type.

Consistent with one embodiment, the video coder/decoder (VODEC) 188 b may be likewise included in the hand-held, portable electronic device 100 to play video items or image files, such as a video file in Windows Media Format (*.wma file) or in a Joint Photographic Experts Group (JPEG) based on JPEG 2000: Image Compression Standards available from International Organization for Standardization (ISO) or MPEG format, or DivX Media Format (*.divx). Another example is a (*.wav), short for Waveform audio format that is a Microsoft and IBM audio file format standard for storing audio on personal computers (PCs). Other examples include the Resource Interchange File Format (RIFF) bit stream format for storing data in “chunks,” the Interchange File Format (IFF) and the Audio Interchange File Format (AIFF) format used on Apple Macintosh computers.

Consistent with one embodiment, a set of base stations may provide wireless connectivity to the hand-held, portable electronic device 100 according to a desirable communication protocol. Examples of a communication protocol include a code division multiple access (CDMA, CDMA2000) protocol, wideband-CDMA (WCDMA) protocol, a Universal Mobile Telecommunication System (UMTS) protocol, a Global System for Mobile communications (GSM) protocol, and like. For example, the hand-held, portable electronic device 100 as a smart phone, text messaging device, and the like may employ a spread spectrum cellular system to operate in a high-speed wireless data network, such as a digital cellular CDMA network.

Referring to FIG. 2 a hand-held, portable electronic device, such as a cell phone 200 is schematically illustrated with a retainable wireless audiophone 105 a capable of attaching to a cell phone housing 205, in accordance with one embodiment of the present invention. The cell phone housing 205 may removably retain the retainable wireless audiophone 105 a capable of wirelessly coupling to communicate with the cell phone 200. The cell phone housing 205 having a surface 210 may removably receive the retainable wireless audiophone 105 a for holding together as a mating pair with the cell phone 200.

In one embodiment, the cell phone 200 may comprise a retainer port 211 that uses a retainer assembly 212 to removably couple the retainable wireless audiophone 105 a to the cell phone housing 205.

To latch itself with the cell phone housing 205, for providing the retainer assembly 212, the retainable wireless audiophone 105 a may comprise at least a second portion 220 a-220 b. Examples of the first portion 215 a-215 b of the surface 210 of the cell phone housing include a cavity 215 having a pair of hollow bubbles so shaped to receive a corresponding solid bubble pair, respectively. Examples of the second portion 220 a-220 b of the retainable wireless audiophone 105 a include a plug 220 having a pair of solid bubbles capable of snugly latching to the corresponding hollow bubble shaped to receive a respective solid bubble of the pair of solid bubbles. However, persons of an ordinary skill would appreciate that the retainer assembly 212 may be formed of many known shapes and structures by having the benefit of this instant disclosure based on one or more factors including a desired application and its operation, location on the cell phone 200. For example, an arrangement of the retainer assembly 212 may comprise the plug 220 and cavity 215. This arrangement may use a known stylus and an associated receptacle structure to securely receive and retain the retainable wireless audiophone 105 a with the cell phone housing 205 at the cell phone 200 by using a mating wedge or tapered forms for the plug 220 and a hollow cone-shaped or wedge-shaped receptacle for the cavity 215 instead of the bubbles based configuration.

Examples of the RF unit 225 include a transceiver based on one or more communication protocols including Bluetooth, Wi-Fi, CDMA, WCDMA, GSM, and General Packet Radio Service (GPRS), a packet-based air interface for radio transmission of data, usually between mobile phones and the Internet.

The cell phone 200 may comprise a baseband unit 230 for digital processing the information signal (voice, data, or image) in the frequency range before being modulated onto a carrier or demodulated after reception by using a signaling technique in which the signal is transmitted in its digital form and not changed by modulation techniques. The baseband unit 230 may comprise a baseband processor 235 for use in a communications system, for example, wireless communications systems and, more particularly, toward baseband processing of communication channels. For example, the baseband processor 235 may be suitable in the United States for a wireless phone service offered in both the cellular (approx. 800 Mega Hertz (MHz)) and PCS (Personal Communications Services) (approx. 1900 MHz) frequency bands in a dual-band phone.

When digital speech represented by a series of bits, which are modulated and transmitted from a base station (not shown) to the cell phone 200, and vice versa, the cell phone 200 may demodulate the received waveform to recover the bits as originally transmitted, and the recovered bits are then converted back into speech. The baseband unit 230 may enable data services, such as E-mail, Internet access, etc., that require digital communications.

In operation, the baseband unit 230 may use one or more types of digital communications systems. For example, FDMA (Frequency-Division-Multiple-Access) systems divide the radio spectrum into a plurality of radio channels corresponding to different carrier frequencies. TDMA (Time-Division-Multiple-Access) systems further divide the carrier frequencies into time slots. D-AMPS (Digital Advanced Mobile Phone System), PDC (Pacific Digital Cellular), and GSM (Global System for Mobile communications) are examples of digital TDMA cellular systems. Alternatively, if the radio channel is wide enough, multiple users can use the same channel using spread spectrum techniques and CDMA (Code-Division-Multiple-Access). IS-95 and J-STD-008 are examples of wireless systems incorporating CDMA standards.

The baseband unit 230 may comprise a RF interface 240 to interface with the RF unit 225. The baseband unit 230 may further comprise a controller 245 and a system connector 250.

The CODEC module 254 and the phone manger module 256 may be software and/or firmware that comprise instructions or program code. The CODEC module 254 may control voice functionality of the cell phone 200. The phone manger module 256 may control the device battery 130 b, the charger circuitry 135, the speaker (SPK) 110 b, and the microphone (Mic) 112 b. The phone manger module 256 may control a subscriber identity module (SIM) 260, a smartcard securely storing the key identifying a mobile subscriber. For example, the SIM 260 may be used with a GSM system or with a compatible module it may be used for a UMTS phone and/or an Integrated Digital Enhanced Network (IDEN) phone. The SIM 260 may store text messages and a phone book. The baseband unit 230 may further comprise a liquid crystal display (LCD) 265, FLASH memory 270, static random access memory (SRAM) 275, a keypad 280, a vibrator 285, and a backlight 290.

Referring to FIG. 13, it schematically illustrates details of the device battery charger circuit 1200 shown in FIG. 12 that replenishes the device battery 1115 of the hand-held, portable electronic device 100 i such as a cell phone according to one embodiment of the present invention. In one embodiment of the present invention, the device battery charger circuit 1200 may be a current-limited voltage source. The device battery charger circuit 1200 may provide to a cell phone battery packs in the battery 3.6-6V DC and 180-200 mA current for charging. The device battery 1115 may comprise one to three Nickel Cadmium (NiCd) cells, each having 1.2V rating. A 12V input with current (1.8 A) may charge the battery connected across the output terminals. The device battery charger circuit 1200 may monitor the voltage level of the device battery 1115. The device battery charger circuit 1200 may automatically cut off the charging process when its output terminal voltage increases above the predetermined voltage level.

The device battery charger circuit 1200 may comprise a Timer IC NE555 to charge and monitor the voltage level in the device battery 1115. Control voltage pin 5 of IC NE555 is provided with a reference voltage of 5.6V by zener diode ZD1. Threshold pin 6 is supplied with a voltage set by VR1 and trigger pin 2 is supplied with a voltage set by VR2.

When a discharged cell phone battery is connected to the device battery charger circuit 1200, the voltage given to trigger pin 2 of IC1 is below ⅓ Vcc and hence the flip-flop in the IC is switched on to take output pin 3 high. When the device battery 1115 is fully charged, the output terminal voltage increases the voltage at pin 2 of IC1 above the trigger point threshold. This switches off the flip-flop and the output goes low to terminate the charging process. Threshold pin 6 of IC1 is referenced at ⅔ Vcc set by VR1. Transistor T1 is used to enhance the charging current. Value of R3 is critical in providing the required current for charging. With the given value of 39-ohm the charging current is around 180 mA.

The device battery charger circuit 1200 may be constructed on a small general-purpose PCB. For calibration of cut-off voltage level, use a variable DC power source. Connect the output terminals of the circuit to the variable power supply set at 7V. Adjust VR1 in the middle position and slowly adjust VR2 until LED1 goes off, indicating low output. LED1 should turn on when the voltage of the variable power supply reduces below 5V. The device battery charger circuit 1200 may use suitable connector for connecting to the cell phone battery, such as the device battery 1115.

Consistent with one embodiment of the present invention, the device battery charger circuit 1200 may power a Motorola make cell phone battery rated at 3.6V, 320 mAH. In place of 5.6V zener, a 3.3V zener diode can be used in this instance. The device battery charger circuit 1200 may provide a charging current of about 200 mA.

Likewise, FIG. 15 schematically illustrates the first headset charger circuit 1205 a shown in FIG. 12 that replenishes the first battery 1120 a of the first attachable wireless audiophone 1110 a according to another embodiment of the present invention.

The first headset charger circuit 1205 a is schematically illustrated according to one embodiment of the present invention to power the first battery 1120 a. The first headset charger circuit 1205 a may charge the first battery 1120 a to 3V operation or provide charge for 5V operation of a battery. As shown in FIG. 14, consistent with one embodiment of the present invention, Maxim IC MAX 1672 that combines a step-up DC/DC converter with a linear regulator for allowing it to regulate up or down for a range of input voltages may be used to realize the first headset charger circuit 1205 a. The first headset charger circuit 1205 a may offer hardware-selectable fixed outputs of 3.3 and 5V; however, 3.3V is out of spec for 3V first or second batteries. With suitably chosen R1/R2/R3 values, see for example, as shown in FIG. 14, one can switch the regulated output between 3V and 5V (or any other two outputs within the allowed range) by applying digital control to the power-good input (PGI). The powergood output (PGO), the output of an internal comparator, then changes the IC's feedback by grounding the node between R2 and R3. If the power-good comparator is in use, one can implement the digital control using the 3/5 input and an external MOSFET, as shown in the second headset charger circuit 1205 b of FIG. 15.
